Abstract
Background Identification of risk factors for hepatitis C virus (HCV) transmission will help in targeted screening of people who are at risk for HCV. Method Indian studies, published between January 1989 and June 2020, were systematically reviewed to identify the relevant studies. We searched electronic databases including PubMed/Medline, Embase, Scopus, and Google scholar to identify the original data published in English language. The full-text studies, published in any form, which reported data on risk factors for HCV transmission among low-risk population were selected. The studies which exclusively included high-risk groups were excluded. Results Data were extracted from 31,176 participants included in 25 studies (median [range] 40 [7-20,113). The participants were HCV infected patients who visited the hospital (n = 10), community population (n = 6), pregnant women (n = 5), blood donors (n = 2), people with diabetes mellitus (n = 1), army recruits (n = 1), or slum dwellers (n = 1). These studies provided data on blood transfusion, use of unsafe injections, minor or major surgery, unsafe dental procedures, tattooing, body piercing, obstetrical procedures, unsafe shaving, intravenous drug use, and unsafe sexual practices as risk factors for HCV transmission. Conclusion Unsafe injections, body piercing, unsafe dental procedure, unsafe shaving, and tattooing were identified as major risk factors for reported by HCV population participants.More data are needed to identify the risk factors for HCV in Indian population. Risk-factor-targeted screening may increase the yield and reduce the cost of HCV screening in India.

Abstract
Sexually transmitted infections (STI) associated with pregnancy poses a great threat to fetal well being due to vertical transmission. This study was conducted to determine the seroprevalence of hepatitis C virus, hepatitis B virus, HIV and syphilis infection in pregnant women. This retrospective study was conducted in Microbiology department over a period of one year from December 2018 to December 2019 at a tertiary care teaching hospital, Uttar Pradesh, India. In this study, hepatitis B surface antigen (HBsAg), antibodies against hepatitis C virus, HIV and syphilis infection were detected in antenatal women. Total 4037 pregnant women attending antenatal clinic were enrolled in this study. The seroprevalence of HBV was 1.34% (54/4037), HCV was 0.52% (21/4037), syphilis was 0.07% (3/4037), and HIV was 0.12% (5/4037). Only one patient had coinfection of HBV and HCV. Regular antenatal screening of all pregnant females for various infections should be done for proper and timely intervention.

Abstract
Background Hepatitis C virus (HCV) infection is high in state of Punjab, however very few studies have been done till date. We all know that pregnant females are a most important section of our community and are usually screened for HCV, HIV, and Hepatitis B at time of presentation. HCV is capable of causing chronic infections and having long-term implications on a person's health. Vertical transmission of HCV can be one of the major route of transmission of this virus to the neonate and there have been various sociodemographic factors like age, literacy, socioeconomic status, occupational status, associated with the disease causation and transmission. Methods All pregnant females attending Obstetrics and gynecology department of our institute were included in study. All the sociodemographic characters and socioeconomic records were retrieved and analyzed. Results In our study also a lower socioeconomic status, illiteracy have been significantly associated with the HCV-positive group, thus emphasizing the role of education so as to impart education to the masses as regard to mode of transmission and its effects on the disease. Higher age of conceiving is also significant associated with the increased maternal risk. Conclusions The more involvement of health care officials and even persons not related to health care set up is required who can educate masses so as to protect the community.

Abstract
Infection with hepatitis C virus (HCV) is a major health problem worldwide. A large proportion of perinatal HCV infections are silent and may present later in adulthood with long-term complications. HCV has no effective immune prophylaxis and hence appropriate follow-up of all infants born to HCV-infected mothers is necessary. Universal antenatal screening for HCV is largely debatable. Intrauterine and partum transmission of HCV are both possible and higher rates are associated with a high maternal serum viral load (> 106 copies per milliliter), concomitant HIV infection, prolonged or difficult delivery, and invasive fetal monitoring during delivery. Infection during pregnancy and infancy needs to be investigated more in order to design management strategies for perinatal transmission of HCV most effectively. The recently approved new-generation, oral, direct-acting antiviral drugs may open a new era in HCV therapy for pregnant women and infected infants if proved to be safe during conception and infancy.

Abstract
BACKGROUND AND AIM Burden of hepatitis C in India is not known. We therefore conducted a systematic review of the available data on anti-hepatitis C virus (HCV) seroprevalence in the Indian population. METHODS We searched several publication databases for English language papers that reported data on anti-HCV seroprevalence from India and also identified other unpublished sources of such data. Data on groups likely to represent seroprevalence in general population and in selected high-risk groups were extracted and subjected to meta-analysis. RESULTS Of the 3995 published papers and 94 additional data sources identified, 327 were selected; these provided 414 anti-HCV seroprevalence data points. Pooled anti-HCV seroprevalence rates in community-based studies, blood donors, and pregnant women were 0.85% (95% confidence interval: 0.00-3.98%), 0.44% (0.40-0.49), and 0.88% (0.21-1.90), respectively. Among groups considered at high risk of HCV, pooled anti-HCV seroprevalence rates were as follows: people living with HIV (40 studies from 17 states: 3.51% [2.43-4.76]), persons on maintenance hemodialysis (37, 13; 19.23% [13.52-25.65]), people who inject drugs (46, 14; 44.71% [37.50-52.03]), multi-transfused persons (38, 12; 24.06% [20.00-28.36]), persons with sexually transmitted diseases (7, 5; 4.10% [0.98-9.04]), and those with high-risk sex behavior (6, 5; 4.06% [1.79-7.10]). CONCLUSIONS Community-based data on HCV seroprevalence in India were limited. Large amount of data on blood donors and pregnant women were identified, with pooled anti-HCV seroprevalence rates of 0.44% and 0.88%, respectively. Among high-risk groups, anti-HCV prevalence was higher among people living with HIV, those with sexually transmitted diseases, high-risk sex behavior or injection drug use, and those receiving hemodialysis or frequent transfusions.

Abstract
Hepatitis C virus (HCV) affects about 3% of the world’s population and peaks in subjects aged over 40 years. Its prevalence in pregnant women is low (1%-2%) in most western countries but drastically increases in women in developing countries or with high risk behaviors for blood-transmitted infections. Here we review clinical, prognostic and therapeutic aspects of HCV infection in pregnant women and their offspring infected through vertical transmission. Pregnancy-related immune weakness does not seem to affect the course of acute hepatitis C but can affect the progression of chronic hepatitis C. In fact, postpartum immune restoration can exacerbate hepatic inflammation, thereby worsening the liver disease, particularly in patients with liver cirrhosis. HCV infection increases the risk of gestational diabetes in patients with excessive weight gain, premature rupture of membrane and caesarean delivery. Only 3%-5% of infants born to HCV-positive mothers have been infected by intrauterine or perinatal transmission. Maternal viral load, human immunodeficiency virus coinfection, prolonged rupture of membranes, fetal exposure to maternal infected blood consequent to vaginal or perineal lacerations and invasive monitoring of fetus increase the risk of viral transmission. Cesarean delivery and breastfeeding increases the transmission risk in HCV/human immunodeficiency virus coinfected women. The consensus is not to offer antiviral therapy to HCV-infected pregnant women because it is based on ribavirin (pregnancy category X) because of its embryocidal and teratogenic effects in animal species. In vertically infected children, chronic C hepatitis is often associated with minimal or mild liver disease and progression to liver cirrhosis and hepatocarcinoma is lower than in adults. Infected children may be treated after the second year of life, given the adverse effects of current antiviral agents.

Abstract
Globally, around 150 million people are infected with hepatitis C virus (HCV). India contributes a large proportion of this HCV burden. The prevalence of HCV infection in India is estimated at between 0.5% and 1.5%. It is higher in the northeastern part, tribal populations and Punjab, areas which may represent HCV hotspots, and is lower in western and eastern parts of the country. The predominant modes of HCV transmission in India are blood transfusion and unsafe therapeutic injections. There is a need for large field studies to better understand HCV epidemiology and identify high-prevalence areas, and to identify and spread awareness about the modes of transmission of this infection in an attempt to prevent disease transmission.

Abstract
Data on transmission of HCV infection from mother to infant in India are limited. Between July 2006 to June 2007, women attending our hospital in the third trimester of pregnancy were screened for anti-HCV. Those testing positive for anti-HCV were tested for HCV RNA. Infants of mothers with HCV infection were followed for up to 24 months. Eight of 488 pregnant women (1.6%) tested positive for anti-HCV; of these, seven had detectable HCV RNA. Two of 7 (29%) children born to HCV-infected mothers had persistently positive HCV RNA, indicating perinatal transmission; one additional child had transient HCV positivity. Passive transfer of HCV antibodies was observed in five babies. HCV infection was detected in 1.4% of pregnant women, and perinatal transmission of HCV to newborns was detected in 29% of such cases.

Abstract
BACKGROUND Maternal morbidity and mortality in low- and middle-income countries has remained exceedingly high. However, information on bacterial and viral maternal infections, which are important contributors to poor pregnancy outcomes, is sparse and poorly characterised. This review aims to describe the epidemiology and aetiology of bacterial and viral maternal infections in low- and middle-income countries. METHODS A systematic search of published literature was conducted and data on aetiology and epidemiology of maternal infections was extracted from relevant studies for analysis. Searches were conducted in parallel by two reviewers (using OVID) in the following databases: Medline (1950 to 2010), EMBASE (1980 to 2010) and Global Health (1973 to 2010). RESULTS Data from 158 relevant studies was used to characterise the epidemiology of the 10 most extensively reported maternal infections with the following median prevalence rates: Treponema pallidum (2.6%), Neisseria gonorrhoeae (1.5%), Chlamydia trachomatis (5.8%), Group B Streptococcus (8.6%), bacterial vaginosis (20.9%), hepatitis B virus (4.3%), hepatitis C virus (1.4%), Cytomegalovirus (95.7% past infection), Rubella (8.9% susceptible) and Herpes simplex (20.7%). Large variations in the prevalence of these infections between countries and regions were noted. CONCLUSION This review confirms the suspected high prevalence of maternal bacterial and viral infections and identifies particular diseases and regions requiring urgent attention in public health policy planning, setting research priorities and donor funding towards reducing maternal morbidity and mortality in low- and middle-income countries.

Abstract
INTRODUCTION Data concerning hepatitis C virus infection during pregnancy in Brazilian medical services are scarce. This study aimed to verify factors associated with vertical transmission (VT) of HCV in pregnant women. METHODS Observational transversal study of pregnant women from Campo Grande, MS, central Brazil, with confirmed reagent serology for HCV infection from 2002 to 2005. Vertical transmission was considered to be positive HCV serology by ELISA, confirmed by PCR, after 18 months of life of the newborn. The factors studied associated with VT were: delivery mode, time of premature rupture of membranes, breastfeeding, blood transfusion history, drug addiction, number of sexual partners and the presence of body tattoos. RESULTS Fifty-eight pregnant women with HCV infection were identified, indicating a prevalence rate of 0.2% (58/31,187). Of these 58 pregnant women,23 (39.6%) fulfilled the inclusion criteria. The VT rate was 13% (3/23), and the most frequent HCV viral subtypes were 1a (53%), 1b (30%), 2b (4%) e 3a (13.0%). Two (8.7%) patients were coinfected with HIV. A significant association (p < 0.05) was observed between VT and high maternal serum viremia (> 2.5 x 10(6)) and VT and the use of illicit drugs by the mother. CONCLUSIONS The present study demonstrates that high serum maternal viremia for HCV and the use of illicit drugs by the mother are associated with vertical transmission of HCV.
